What is Hubble's Law?

Back

It states that the velocity at which a galaxy is receding is directly proportional to its distance from us.

Front

What is a habitable zone?

Back

The region around a star where conditions may be suitable for life, typically where liquid water can exist.

Front

What is the significance of Barnard star's temperature?

Back

Barnard star's surface temperature is about 54% of the Sun's temperature, influencing its potential for habitability.

Front

What does the H-R Diagram represent?

Back

The Hertzsprung-Russell Diagram plots stars according to their luminosity and temperature, helping classify them.

Front
